Tools are provided for estimating, testing, and simulating
abundance in a two-event (Petersen) mark-recapture experiment. Functions are
given to calculate the Petersen, Chapman, and Bailey estimators and associated
variances. However, the principal utility is a set of functions to simulate
random draws from these estimators, and use these to conduct hypothesis
tests and power calculations. Additionally, a set of functions are provided
for generating confidence intervals via bootstrapping. Functions are also
provided to test abundance estimator consistency under complete or partial
stratification, and to calculate stratified or partially stratified estimators.
Functions are also provided to calculate recommended sample sizes.
